Dynamic range of microbolometer I would like to know why the microbolometer of FLIR has 14 bits dynamic range when most of the information about microbolometers says it is limited to 12 bits. The analogue to digital converters in many bolometer cameras are 14 bits or more. However, the usable dynamic…

How is NEDT measured? NEDT (noise equivalent differential temperature) is the key figure of merit which is used to qualify midwave (MWIR) and longwave (LWIR) infrared cameras. It is a signal-to-noise figure which represents the temperature difference which would produce a signal equal to the camera’s temporal noise. It therefore represents approximately the…

Under the Volcano: FLIR Systems cameras used to monitor active volcanoes If an infrared camera is the instrument to detect and measure hot spots, it must be the perfect tool to survey the biggest and most impressive hot spots on earth: volcanoes. Italy is home to at least two…

We don't use D* because it is an obsolete figure of merit which was used to compare single element detectors. It does not work well for comparing FPA type detectors. It has been replaced by NEDT by the industry because there are no assumptions or approximations in the calculations…
